Renewable energy?

   Maybe the best way is to look at how nature generates the energy it needs for its everyday, renewable, clean and ecological needs: by harnessing power coming from the sun and converting it to chemical energy. Our best bet is to use the enormous amount of energy that the Sun delivers to our planet everyday, in the same way plants do using photosynthesis.

   plant trees and other plants to replace the ones used in building etc etc
   recycling is also good, reduces energy and materials used..

   Well… most energy is not really "renewable." What we need to have is efficient energy sources, like the Sun. If we could capture the energy the Sun produces in one second, then we could power the Earth for the next thousand years easily.
   The most efficient power source would be antimatter. When antimatter meets matter it converts directly to energy according to E=mc^2. This is the dream of every environmentalist, physicist, astronomer, and so on. Unfortunately we can only create antimatter in high tech laboratories, and we can only study it for fractions of a second before it annihilates.
   Other energy sources that we use today that are more "renewable" are river/waterfalls and wind. Wind is unreliable for obvious reasons, and you can only put hydroelectric (water powered) plants at certain places.
   Power is a real problem today, and it is getting worse. We need to do all we can to find a reliable and large power source.
